AI Technical Summary

Technical Problem

Existing hearing aids lack the ability to recognize the evolution of the sound field and the mechanism for smooth parameter transitions in complex home environments, leading to environmental misjudgments, abrupt parameter changes, and parameter drift during quiet periods, which affects auditory comfort.

Method used

Sound signals are collected by intelligent sensors, and sound pressure level, direction of arrival, relative energy ratio of sound sources and spatial relationship features are extracted to form a multi-dimensional feature vector. Combined with the template center distance, sound field changes are analyzed, and transition control factors are generated for parameter interpolation to achieve a smooth transition.

Benefits of technology

It improves the accuracy of environmental discrimination, avoids frequent false switching, ensures continuous and gradual changes in audio parameters, reduces interference from low signal-to-noise ratio silent segments, and guarantees the smoothness and stability of auditory output.

Abstract

The application discloses a hearing aid audio signal processing method and system based on intelligent sensors, relates to the technical field of hearing aid audio signal processing, and comprises the following steps: collecting an environmental sound signal and combining a feature vector; calculating a first distance from a living room template center and a second distance from a kitchen template center, forming a difference sequence and performing time sequence evolution trend analysis, determining a sound field change category, and generating a transition control factor; using the transition control factor as an interpolation weight to interpolate living room mode and kitchen mode benchmark parameter groups, generating tentative output audio parameters and calculating a signal-to-noise ratio; forming an absolute energy envelope based on target sound source frequency band energy and calculating a short-time energy variance to output an activity state flag; and according to the activity state flag and the signal-to-noise ratio, freezing or updating the transition control factor, and outputting the tentative output audio parameters after maximum step limiting amplitude processing. The application realizes smooth adaptive switching of a hearing aid in a home environment.
